For end user configs @a47ae 's suggestion is fine. A second config file maybe in cson or yaml to make it easy for end users is best. That’s not needed as part of quasar. Env variables would be fine for cases where just one or two things need to be set by end user. But for custom “built in” settings for the quasar app itself (not for end users) being able to set and grab them from quasar.conf would be nice.
